BOX-FASTENER.

Specification of Letters Patent.

Patented Sept. 22, 1908.

To all whom it may concern:

Be it known that we, ALVIN T. Tnorrs and same.

()ur invention relates to improvements in box fasteners, and more particularly to fastoners for use on fireles s cookers, and its obect is to provide a strong and secure device that will yieldingly clamp the cover in closed position, and to rovide the same with various new and use 1 features hereinafter more fully described and particularly ointed out in the claims, reference being ha to the accompanying drawings, in which:

Figure 1. is a front elevation of a device embodyin our invention; Fig. 2. a side elevation oft e same; and, Fig. 3. a perspective of the same.

Like numbers refer to like parts in all of the figures.

1 represents the side of a box to which the device is ap lied; 2 the cover of the box.

Secured to t e cover is a hook formed of a piece of wire folded at the middle and having diverging arms terminating in eyes or loops 3 to receive fastenings 6, preferably screws inserted therein and extending into the cover. The middle portion of this wire is bent downward at right angles as at 4 extending over the corner of the cover and opposite the edge of the same. It is thence turned outward and upward forming a hook 5 to receive the link member. A bar 7 formed of a iece of wire extends horizontally on the side of the box below the hook 5, having its middle portion spaced apart from the box, and its ends provided with loops or eyes to receive fastenings consisting of screws 8 inserted in the side of the box, whereby the bar is securely held in place. Pivoted on this bar by means of eyes or loops 9 formed in the respective ends of the same, is a lever made of wire having its respective ends spaced apart and extending from the bar? to a proper distance to form a lever, at about the middle of which the wire is bent inward at right angles having poFtions 11 in horizontal alinement, the remaining portion of the lever being formed into a handle portion 16 consisting of the middle portion of the wire folded or bent upon itself and extending parallel and close together. Pivoted upon the horizontal portion 11 of this lever member by means of loo s or eyes 12 in its respective ends is a U-s iaped link having parallel sides 13 extending between the portions 10 of the lever, the upper end of th1s link being bent rearward as at 15 and havin" its middle horizontal portion 14 detacha ly enga ed with the hook 5. This rearward bend in the upper part of the link serves to render the lin somewhat 'elding to operate as a spring to effectually clb se the cover and ermlt the lever to spring inward to place. t. also permits the pivotal connection of the link and the lever to ass below the bar 7 and closer to the side 0? the box. The pivotal connections of the lever to the bar and to the hook are thus nearer to the box than the bar 7, whereb the strain on the link tends to securel old the device in closed position.

W at we claim is:

l. A box fastener, com rising a hook adapted to be attached to a ox cover, a bar adapted to be attached to a box at its respective ends, and having its middle s aced apart from the box, a lever pivoted to the bar, and a link ivoted to the lever and adapted to engage t e hook.

2. A box fastener com irising a hook made of a piece of wire folde at the middle and formed into a hook, and having diverging arms each terminating in an eye to receive a fastening, a bar bent outward at the middle and having each end terminating in an eye to receive a fastening, a. lever formed of a wire having its ends pivoted on the bar and having parallel sides spaced :1 art and also having middle horizontal an inwardly turned portions and a handle portion formed of the folded middle part of the wire, and a wire link pivoted on the horizontal ortion of the lever and ada ted to engage t e hook.

3. A box astening, comprising a. hook adapted to be fastened to the cover of a box, a bar adapted to be fastened to the side of a. box and'bent outward at the middle, a lever pivoted to the bar, and a link pivoted to the ever at one end and adapted to enga e the hook at the other end, said link also being bent to atl'ord a yielding connection and to 119 permit the ends of the link to pass the plane of the bar.

4. In combination with a box having a cover, a wire folded at the middle, formed into a hook and bent downward opposite the edge of the cover, diverging arms to the wire each terminating in an eye and extending on the top of the cover, screws inserted in ach ego and in thev cover, a bar spaced apart from t e side of the box and having its ends bent toward the box and each end provided with an e e, a screw in each eye and inserted in the x, a lever consisting of a wire having an eye in each end surrounding the bar, parallel portions extending from the bar and spaced apart, alined inwardly turned portions, and a handle portion formed of the folded middle portion of said wire; and a link formed of a wire havin r a loop in each end surrounding the inward y -turned portions of the lever, and a horizontal middle portion to engage the hook, said link also being bent to extend rearward above the bar.

5. In combination with a box having a cover, a wire hook attached to the cover and extendin downward opposite the edge of the same an thence outward and upward, and also having diverging arms secured to the top of the cover, a bar secured to the box below the hook and spaced apart from the side of the box at the middle, a toggle lever consisting of a iece of wire folded at the middle to form a andle, thence extending outward horizontally near the middle and thence extending upward parallel and spaced apart and also pivoted at the respective ends on the bar, and a link having a horizontal middle portion engaging the hook and thence extending downward between the parallel ortions of the lever, and. pivoted at its enc s to the horizontal portions of the lever.

In testimony whereof we allix our signatures in presenceof two Witnesses.
